Life time&colon; 3000-5000hoursHRC&colon; 58-66 &lpar;surface&rpar;Diameter&colon; TO THE REQUST OF THE CUSTOMERSMaterial&colon; Corrosion-resistant&comma; bearing steelCorrosion resistance&colon; HighScoring resistance&colon; High

Advantages&colon;--simple&comma; reliable design--high sealing effect against dirt&comma; water and abrasive media from the outside and against oil and grease from the inside--cost-effective--long service--maintenance-free--easy to assemble

Applications&colon;Mechanical Face Seals are predominantly used for sealing the bearings in construction machinery or production plants operating under extreme arduous conditions and subject to severe wear&period;

These include&colon;- Tracked vehicles&comma; such as excavators and bulldozers- Conveyor systems- Heavy trucks- Axles- Tunnel boring machines- Agriculture machines- Mining machinesMechanical Face Seals are proven in general machine engineering for gearboxes&comma; mixers&comma; stirrers&comma; wind-driven power stations and other applications with similar conditions or where maintenance-free lifetime time sealing is expected&period;
